Control matlab, there are many kinds of electronics, and I can't tell the rest after searching a lot on the Internet, but matlab is definitely a powerful simulation software.

To put it bluntly, simulation is a means of mixed graduation (except for those who engage in theory). If you really want to write a graduation thesis to prepare for graduation, you will know why to use simulation (if there is no simulation, you must have actual data to prove your conclusion), and you will also know what books introduce simulation. The higher the educational background, the more obvious the composition of mixed graduation.
